Title: Sheath around collapsed flexible lining for rigid container - locates and gradually releases lining during filling with liquid from below to smooth out creases
Inventor: NITTEL WALTER DR
IPC: B65D77/06
Filed: 1979-01-12
Abstract: The sheath is intended for lacting a collapsed foil lining inside a rigid container (24) during filling with liquid from below.

Title: Mains rectifier synchronisation control - has phase shifter with active filter comprising operational amplifier and multiplier
Inventor: SCHRAEDER ALFONS DIPL ING
IPC: H02M1/08
Filed: 1979-04-24
Abstract: The circuit ensures filtering of the synchronising voltage for reliable operation of simple unit controlling the mains-driven rectifier. At the same time, correct functioning even in the case of significant frequency variations is safeguarded using the 1st order active filter for phase shift depending on the frequency change. The filter receives a frequency-depending signal for phase shift correction, and comprises an inverting amplifier (3), capacitor (1), and resistors (5, 6). The amplifier is of the operational type and feeds the multiplier (2) while the input of the multiplier is connected to the function generator (4). This ensures the feedback of the circuitry by providing compensation control.

Title: Cutting and conveying appts. for green bricks - divides length of clay into short sections which are separated and turned through 90 degrees
Inventor: OBERSTE-KELLER CLEMENS ING GRA
IPC: B28B13/04
Filed: 1979-05-29
Abstract: The appts. is used by conveying long hole raw or green bricks (7) until taken over by carrying supports. The raw bricks produced forming a batch are cut off from a hank of clay. The batch is cut into raw bricks transverse to its longitudinal direction, with the bricks subsequently conveyed onwards lying closely together transverse to the longitudinal direction of the transverse row produced by the cutting process. The bricks are transferred to carrying supports in such a way that the elongated holes located in the raw bricks extend transverse to the length of the carrying supports. The transfer process includes a number of stages for drawing apart the raw bricks into gaps in longitudinal rows and subsequent turning of the raw bricks by 90 degrees round their vertical axis.

Title: Heat treatment of thin section aluminium alloys - by soln. treatment, quenching and three-stage tempering
Inventor: DUBOST BRUNO
IPC: C22F1/053
Filed: 1979-08-09
Abstract: This prod. (equivalent thickness 15 mm) of Al alloy 7000 series of the Al Zn-Mg-Cu type contg. 0.4-5wt.% Cu, are heat treated by soln. treatment, quenching and tempering. Specifically a pretempering of 5 mins - 24h at 100-150 degrees C, an intermediate tempering and a final tempering of 2-48 h at 100-160 degrees C are carried out. The intermediate heat treatment consists of an increase in temp. at >=1 degrees C/min. from 150-190 degrees C followed by an evolution of the temp. of the product as a function of time (T), i.e. (T), including a temp >=190 degrees C for part of the time, over a total time T such that the value of the function. lies between 0.5 and 1.5. In this equation T is the total time in seconds for this step counted from the moment where the temp passes 190 degrees C, increasing, for the first time. O(T) is the temp in degree K of the coldest part of the prod. above 190 degrees C and below 250 degrees C (235 degrees C), and t is the time in secs. Used esp. with sheet, strip, tube, bar, profile etc. The process avoids introducing a very poor resistance to corrosion under tension in the tranverse direction, inhibiting exfoliating corrosion. These faults are introduced by the normal heat treatment method.

Title: Fish processing reactor - with heating zone for protein coagulation and wash-out zone for oil and fat
Inventor: TRONSTAD INGE M DR ING
IPC: A23L17/00
Filed: 1979-09-13
Abstract: Material of animal origin, esp. fish and fish paste, is processed by heating it to a temp. which is high enough to initiate the coagulation of the proteins contained in it. This is done in a first section of a reactor. In a second section, fat and oil are washed out from the coagulating material at a controlled temp. The result is a higher oil yield. The dry end prod. contains a min. of fatty substances. This improves its shelf life and makes it more suitable for conversion into fish meal.

IPC: H04R3/00
Filed: 1979-10-22
Abstract: In order to adapt the preferable characteristics of a crystal microphone to the performance requirements set for post office carbon microphones and thereby creating the possibility of replacing the latter, the invention provides across the crystal microphone (1) the gate/source connection of a field effect transistor (3). The terminals of the microphone housing in a telephone subscriber station connect to the drain/source terminals via a high resistance (2). To make the device independent of polarity, diode pairs (6) precede the transistor. The operating point can be selected with the aid of a further resistor (5) and should be chosen to yield a drain current of about 30 mA and average voltage slope of 200 mS with the average drain voltage becoming 6 volts. The diode network may be replaced by complementary VMOS transistor with its gate connected to the gate of the p-enrichment field effect transistor. Both versions can be readily integrated.

Title: Vibration damping system for resiliently-mounted combustion engine - uses servo system to alter fuel-air mix to counteract sudden speed changes
Inventor: BUFLER ERNST DIPL ING
IPC: B60K5/12
Filed: 1979-12-19
Abstract: The system detects sudden changes in the vehicle speed and alters the fuel/air mix supplied to the engine in such a way that the sudden change is counteracted. The system detects when a given positive or negative acceleration is exceeded and then alters the mix. The second time derivative of the vehicle speed is formed and used to control the mix. A signal describing the movement of the accelerator pedal is used to control the mix in that it acts as a feedback signal. The mix is adjusted by e.g an electric servomotor (1) that uses the feedback signal.

Title: Yarn winder reciprocating drive - has two cam rollers to allow stroke length changes without end adjustment
Inventor: GRAU GERHARD DIPL ING
IPC: B65H54/28
Filed: 1979-12-24
Abstract: The cam roller, for the yarn guide's reciprocating drive, is keyed to its drive shaft to allow axial movement. It is connected in series with a second cam roller, to be engaged and disengaged, and the continuous curve gives a preset short stroke length. This is keyed to a mechanical tracer. One of the two tracers runs parallel to the rotary axis of the drive shaft, to carry the yarn guide along its reciprocating path. The second cam roller can be locked to the first roller in at least two positions, at relative angles to each other, to give a stroke length change for the movement of the yarn guide. The two rollers are secured to each other at their end faces, and their curves can be positioned to be in the same phase, or at 180 deg. to each other. The design ensures that the points of direction change do not require adjustment when there is a stroke length change.
